APPARATUS FOR PREPARING ASPHALTIC CONCRETE FOR PAVING PURPOSES.

EPECIPICATION forming part of Letters Patent No. 348,492, dated August31, 1886.

Application filed May 21, 1886. Serial No. 202,596. (No model.)

To all whom it may concern:

Be it known that I, Farmers V. GREENE, a citizen of the United States,residing at New York, in the county ofNew York, State of New York, haveinvented certain new and useful Improvements in Apparatus for PreparingAsphaltic Concrete for Paving Purposes, of which the following is aspecification, reference being had therein to the accompanying drawing.

My invention relates to improvements in devices for the manufacture ofasphalt-concrete for the laying of streetpaven1ents.

The object of my invention is to provide a device for makingasphalt-concrete, which can be moved from place to place and readilybrought to a convenient distance from the point where it is to be usedor laid in the street, so that the material will not be chilled orcooled too much before it is laid in position.

In large cities, as in New York and elsewhere, the works for heating thesand or crushed stone and melting and mixing the asphalt with the sandor stone to form a concrete are necessarily some distance from the placewhere it is to be used, and frequently the material must be hauledseveral miles. This hauling of the material such long distances is notonly expensive, but the material becomes chilled to such an extent thatit cannot be laid in a proper manner so as to form a perfect bond.

My invention therefore consists in mounting the heater, melter, mixingdevice, and other necessary devices on a boat in such convenientrelations to each other that they can be used conjointly in themanufacture of the asphaltconerete, the boat being adapted to be movedfrom one wharf to another, so as to be within a convenient haulingdistance of the place where it is to be used.

In the drawing I have shown a top or plan view of a ship or vessel 011which the devices are mounted.

A indicates the vessel or ship, which may be of any approvedconstruction suitable for the purpose, and provided with an engine, B.

The engine is by preference located in the stern and hold of the vessel,and adapted to drive the propellers C, when it is desired to move theboat from one landing or city to air other; but when the boat is inposition or at anchor the engine is adapted to be used to drive theheater and mixer by means of a fast and loose pulley mounted on theshaft D,whieh communicates power to the heater E through the band orendless belt F, while the mixer G is driven or operated by means of theendless belt or band II. I

I is the melter, in which the asphaltum is melted or liquefied, saidmelter being arranged in such relation to the mixer that the meltedasphalt can be readily carried or conveyed thereto by means of thebucket or vessel K, which is adapted to travel back and forth from themelter to the mixer on the ways or track L.

The melting, mixing, and sand-heating de vices are not described indetail in this application, but are essentially of the same construction as shown, described, and claimed by me in an application filedMay 24, 1886, Serial N 0. 203,150.

It maybe proper to state in this connection that the heating, mixing,and melting devices are mounted on the upper deck of the vessel, so thatthe carts can be readily loaded by means of any suitable labor-savingdevice such as an endless carrier or trough running from the bottom ofthe mixer-and that the front part of the hold or lower decks of thevessel can be utilized for the storage of the asphaltum, sand, and othermaterial, or a portion of the lower decks can be arranged as berths,dining-room, and kitchen for the ac eommodation of the laborers.

Suitable elevators may be used to raise the material from the hold anddeposit it in the heater or melter, and the various deviees'arranged insuch relation to each other as may be most convenient or advantageousfor the rapid manufacture of the asphaltic concrete.

By mounting the devices on a vessel in the manner described I am enabledto move the plant from one point to another, and to prepare the materialat a place near the street to be paved, so that the concrete can bedelivered without losing the heat to any great extent.

A further advantage of my invention is that I am enabled to move myentire plant without 2. A plant for the manufacture of asphalticconcrete for paving purposes, consisting of a boat with propellers andengine for driving the same and the heater and mixer adapted I 5 to bedriven by the same engine, as set forth. In testimony whereof I affix mysignature in presence of two witnesses.
